CREASING MECHANISM FOR SHEET COIELECTING AND FOLDING- MACHINES.

Specification of Letters Patent.

Patented Aug. 15, 191%..

Application filed November 15, 1913. Serial No. 801,298.

To all whom it may concern:

Be it known that I, HOWARD M. BARBER, a citizen of the United States, and resident of Stonington, in the county of New London and State of Connecticut, have invented a new and useful Improvement in Greasing Mechanism for Sheet Collecting and Folding Machines, of which the followmg 1s a specification.

The object of this invention is to provide means for creasing folded signatures so that when the signatures are superposed or gathered and secured together, as by stapling, the magazine or book thus formed, will lie open at any particular page.

A further object is to crease a signature which has been folded transversely of its travel, said crease being imparted to .the folded signature at a predetermmed distance from its back or folded edge and parallel thereto.

A still further object is to reversely crease the so folded signature so that each leaf of the book or magazine formed from a collection of signatures will readily fold back either way along the crease thus formed.

A practical embodiment of the 1nvent1on is represented in the acoompanymg drawings, in which, I

Figure 1 is a view in side elevat1on 0f so much of a collecting and folding machme as will give a clear idea of my invention applied thereto. Fig. 2 is a vertlcal section taken within and adjacent to the farther side frame of the machine. Fig. 8 is a detail diagrammatic section taken centrally through the machine from front to rear. Fig. 4 is an enlarged detail section showing the parts in the position which they assume when the first crease is being imparted to the folded signature. Fig. 5 is a similar view showing the parts in the position which they assume when the second or opposite crease is being imparted to the folded signature along the line of the first crease. Flg. 6 is a detail face view of the creasing blade on the scale shown in Figs. 1 and 5, and Fig. 7 is a detail section showing a modifled form of the first creasing roll.

The two side frames of'the machines are denoted by 1 and 2. The web feed roll is denoted by 3, which roll is suitably mounted in the side frames 1 and 2. The pair of rotary cutters 4 and 5 have their shafts 6 and 7 mounted in the side frames of the machine, which cutters are, in the present instance, shown as provided with three sets of coacting blades 8, 9, arranged to cut the web 10 into three sheets for each revolution of the cutters.

The sheet collecting cylinder 11 has its shaft 12 suitably mounted in the side frames ofthe machine, which cylinder is shown as being provided with three sets of grippers 13, 14, 15, with three intermediate collecting surfaces. The collecting cylinder 11 is provided with three tucking blades l6, l7, 18, located intermediate the grippers 18, 14, 15, which blades are arranged to successively coact every one and one-third revolutions of the collecting cylinder 11, with the floating folding jaw 19 carried by the rotary carrier 20, the shaft 21 of which is suitably mounted in the side frames of the machine. In the arrangement of the parts as herein shown, the cylinder 11 collects four sheets cut from the web on each collecting surface and folds off the collected group of four sheets to the rotary carrier 20.

The cam mechanism for insuring the proper opening and closing of the collecting cylinder grippers, the folding on of the collected sheets to the floating folding jaws 19 and for controlling the floating of said jaws will not be specifically described herein as they may be of any well known or approved form and are not a part of the present invention, which invention is directed to the creasing of the folded signatures, the mechanism for which will now be described.

The shaft 22 of the delivery cylinder 23, is mounted in suitable bearings in the side frames 1 and 2 of the machine. This cylinder is provided with a set of grippers 24 arranged to take the folded signature from the folding jaws 19 of the rotary carrier 20 and deposit the signature after it has been slit longitudinally of its travel, into a plurality of smaller signatures. In the present instance, a portion of a pocketed carrier 25 is shown for receiving the signatures from the delivery cylinder 23. A shaft 26,1nounted in spring-pressed hearings in the side frames of the machine, carries one or more slitting disks 27 arranged to coact with one or more circumferential grooves 28 in the delivery cylinder 23, for slitting the folded signature into two or more sections as desired '1 Creasing rolls 29, 30, have their shafts 31, 32, mounted in suitable"spring-pressed bearings carried by the side frames of the machine. V A creasing-blade 33, works inwardly and outwardly in a slot 34 in the periphery of the delivery cylinder 23. This blade is guided in its'movements by pins 35 passing through elongated slots 36in the blade. 1 The inner edge of this blade 33 is seated V infja transverse holder 37 having studs rotatably mounted in the free ends 0f the arms 39, fixed to a rock shaft 40. This rock shaft is provided with a rocking arm 41 exterior to the delivery cylinder, which arm carries a stud or roller 42 arranged in position to be engaged by a fixed cam 43 for moving the creasing blade outwardly. A

, spring 44-ona rod 45' attached to the free end of the arm 41 and having a sliding engagement at 46, with the delivery cylinder,

- servesto normally move the creasing blade 25 to the limitof its inward movement.

j The first creasing roll 29is provided with a groove 47 for receiving the outer edge of the creasing blade when it is moved out- I wardly to form the first crease in the folded signature. In'Figs. l to 6 inclusive, this groove 47 is shown as located in a block 48 of yielding material seated in a suitable holder 49, and in Fig. 7, this groove is shown formed directly in the roll.

The second creasing roll 30 is provided with a fixed creasing blade 50 projecting slightly beyond the periphery of the roll,

which creasing blade is arranged to enter the slot 34 when opposite the same, for imparting the second crease in the opposite direction along the line of the first crease.

A fixed cam 51 is located in position to engage the stud roller 52 on the rock lever 53 of the set of grippers 24, to open the grippers for receiving the folded signature from the'rotary carrier 20, and a fixedcam 54 is arranged in position to engage the said stud roller52, for opening the grippers to on the three' way collecting cylinder 11, and

successively folded off therefrom to the rotary carrier 20. This rotary carrier 20 transfers the folded group of sheets to the delivery cylinder 23, where the signature is slit longitudinally into the desired number of sections and is creased transversely to its travel and parallel to the fold by the coaction of the movable creasing blade 33, with the groove 47 in the first creasingroll 29. As the signature continues its movement, it is creased inwardly along the line of the outward crease by the coaction of the fixed creasing blade 50, on the second creasing roll 30, with the groove 34 in. the delivery cylinder. This reverse creasing of the signature adjacent to its folded edge and parallel thereto, will permit each of the leaves to be readily turned back andforth on the said reverse crease as a hinge, permitting the book or magazine formed from a signature or a collected group of signatures to be readily opened and when open, to lie fiat at any particular portion thereof.

It is evident that various changes may be resorted to in the construction, form and arrangement of the several parts without departing from the spirit and scope of my invention; hence I do not wish to limit myself to the construction herein shown and described, but

What I claim is:

1. In a machine of the character described, means for folding a signature and means for creasing the signature parallel to the fold.

2. In a machine of the character described, means for folding a signature transversely of its travel and means for creasing the signature parallel to the fold.

13. In a machine of the character described, a cylinder for carrying a signature, two creasing rolls and means carried by the cylinder and rolls for reversely creasing the signature.

14. In a machine of the character described, a cylinder having engaging means for carrying a signature to a predetermined point, a creasing roll and means carried by the cylinder and roll for creasing the signature transversely of its travel.
